The ESC1 EGO Signal Conditioner alters the signal from EGO sensors under boost conditions. It may be used in either single or dual EGO sensor applications. Under vacuum conditions, it outputs a signal which is identical to the EGO signals that appear at the input. Under boost, it outputs an internally generated signal to allow open loop operation.
The ESC1 is especially useful for forced induction conversions where a supercharger or turbocharger is fitted to an engine which is normally naturally aspirated. In the vacuum region of operation, the ECU operates in its normal closed loop mode of operation. Under boost, the ECU transitions into an open loop mode and maintains its internal mapping tables.
The ESC1 allows the conversion to forced induction on engines with modern fuel injection, including those with OBDII onboard diagnostics. The stock ECU programming may be used without activation of fault codes under boost.
For use with front Oxygen Sensor equipped vehicles. Not for use with Air Fuel Ratio Sensor equipped vehicles. |
